Just as there are free applications and other fee, free and paid games, so there are also images that can be used by all for free and without limits and others that their use requires copyright and a recognition that can also be expressed in money or at least in a quote.
For an online project is required so don't take pictures or images of others without permission, not to republish them as if they were our own, though.
When we talk about free images, there are three terms that you will encounter in the search.
-Images of type "Royalty-free"
- Public domain pictures that are not covered by copyright, available for free for any use, without any permission.
- Images with Creative Commons license, not public, but free to use.
Creative Commons is a collection of free licenses for the fair use of digital products.
The images with this license are free, with restrictions expressed by the license itself such as the prohibition on edit or use for commercial purposes or the requirement of attribution.
